10.23 HEAT RECOVERY DISABLING SIGNAL DUE TO HIGH CONDENSATION
TEMPERATURE/PRESSURE IN COOLING WORKING MODE
Alarm code
b1rC…b4rC (circuit n° 1…4 recovery disabling alarm)
Display in keyboard
Recovery dis.hi t/p C1…Recovery dis.hi t/p C4
Cause of activation
RC01=3, if the probe for disable heat recovery (configured as condensation
temperature or pressure) measures a value >= rC07 set, alarm occur.
Reset
 The condensation pressure or temperature probe measures a value <=
rc07 set – rC08 differential
 Heat recovery disabling function is intervened due to Par. rC09 time
expired.

10.24 UNLOADING SIGNAL DUE TO LOW EVAPORATION PRESSURE IN HEATING WORKING MODE
(Not available)
Display label meaning
b1Eu (circuit n° 1 unloading from condenser coil signal)
b2Eu (circuit n° 2 unloading from condenser coil signal)
b3Eu (circuit n° 3 unloading from condenser coil signal)
b4Eu (circuit n° 4 unloading from condenser coil signal)
Display in keyboard
Unload lo press.circ1…Unload lo press.circ4
Cause of activation
When working, if the probe configured as condensation temperature,
configured as pressure control or as evaporation pressure, measures a value <
Un13 set
Reset
 if the condensation pressure/temperature or the evaporation pressure
measures a value > Un13 + Un14
 With unloading function inserted after the time set Par. Un15
